3. (2 pt) Write a script that enables you to calculate and display factorial of n, i.e, n! (https://www.mathsisfun.com/numbers/factorial.html). Let's use n 5. Note: this script should include loop statement AND "fprintf to control the loop and print the outcomes on the screen. You may need to write a script (m-file), i.e., "facto Al111B222.m" to provide Matlab/Octave command shown below. clear all % clear all the variables that you have used. n = 5; % n for factorial n your script should be given here] while (i > 1) [your script should be given here] end fprint f ('factorial of % -n, nFactorial); You need to turn in Octave (or Matlab) output by running the developed script, facto A111B222.m in the command window as given below >>facto_A111B222 factorial of 5 = 120

Explanation / Answer

LOGIC : The factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n.

i.e. n! = n*(n-1)*(n-2)*(n-3)*..........2*1

Script name : facto_A111B222.m

CODE :

clear all; % clear all the variables used before

n=5;

fact=1;

i=5;

while (i>1)

fact = fact * i;

i = i - 1;

end

fprintf('factorial of %d = %d ', n, fact);

OUTPUT :

>>facto_A111B222<enter>

factorial of 5 = 120
